I have the following:
Windows 10 Pro Insider Preview Build 10130
Dell XPS 8500 (Latest BIOS A12)
AMD Radeon HD 7700 (15.5 Beta Driver 14.502.1014.1001 for Win 8.1 64 bit, which is downgraded from Engineering Sample WDDM 2.0 Driver 15.200.1023.5)
Plugable UGA-3000 (Latest DisplayLink Beta Driver for Win10)
I cannon get the device to stay connected. I get the USB connect sound, an attempt to display, then the disconnect sound. I have followed all the advice I can in the support document on that issue to no benefit, adjusting BIOS USB settings, power plan USB settings, trying different USB ports, and so on. I also have an older UGA-2K-A Rev B that displays the same behavior. Every so often, the screen will connect and look good - but it lasts only a moment and then I get the disconnect sound again. The one thing I have left to do is a powered USB hub or Y cable.
I have other Win10 devices with Plugable products working fine.
I do notice this in the Plugable UGA-3000 Events log: Device USB\VID_17E9&PID_4324&MI_00\6&3550058c&0&0000 requires further installation.
I’m trying to attach a zipped log file, but don’t know where to do that here.
